Working at Height Certification

The Working at Height Certification is a free intermediate-level, 20-minute skill test from Science of Apps. It tests working-at-height safety knowledge — planning with the hierarchy of controls, fall prevention and fall arrest systems, ladders, roofs and access equipment, and inspection, rescue and training — written to the UK Work at Height Regulations 2005 and HSE guidance and OSHA fall protection standards (29 CFR 1910 and 1926) for 2026. Practical training and equipment familiarisation are still required. Score 70% or more on its 20 questions to earn a verifiable Working at Height Proficiency certificate (SOA-WAH).

Yes. The questions are original scenarios written by Science of Apps, and each one is based on a public source you can read: 29 CFR 1910.140 Personal fall protection systems (OSHA); Work at height: the Work at Height Regulations 2005 (UK Health and Safety Executive); Safe use of ladders and stepladders (UK Health and Safety Executive); Fall protection (OSHA); 29 CFR 1926.502 Fall protection systems criteria and practices (OSHA); Stairways and ladders: a guide to OSHA rules (OSHA). The source is shown under each question and linked in the answer review. Science of Apps doesn't copy questions from other tests.

Four skill areas with five questions each, drawn from a bank of 10 per area so a retake brings new questions: Planning and the Hierarchy of Controls (Risk assessment, Collective vs personal protection and Legal duties); Fall Protection Systems (Restraint and arrest, Anchors and harnesses and Clearance); Ladders, Roofs and Access Equipment (Ladders, Fragile surfaces and Platforms and MEWPs); Inspection, Rescue and Training (Equipment inspection, Rescue planning and Competence). Every question is an original scenario written to the 2026–2027 standard, with the published source named under it.

Construction or maintenance worker, Roofer or installer, Facilities or warehouse staff, Site supervisor or safety officer and Telecoms, solar or window-cleaning technician. It suits anyone who wants a quick, verifiable way to show Working at Height knowledge in 2026 and 2027, from students and career switchers to experienced professionals.

It covers recognising fall hazards, planning work to avoid or prevent falls, choosing and using guardrails, platforms, ladders and personal fall protection, inspecting equipment, and planning rescue. Many countries require employers to train workers before they use fall protection.

In the UK, the Work at Height Regulations apply to any work where a person could fall a distance liable to cause injury, with no minimum height. In the US, OSHA generally requires fall protection at 4 feet (1.2 m) in general industry and 6 feet (1.8 m) in construction.
